To all whom it may concern: v and without reversing the bottle. This re-Be it known that l, .UrunLEs FRANCIS salt is attainetLby providingaplunger which 65 JnNn Ns, a citizen of the United States, recuts anopening in a paper strip, a plunger siding at Washington, in theDistrict of and die which cut from the strip a disk in- 5 (olnm-bia,have invented certain new and (finding the perforated part, form-r draw.useful Improvements in Machines for Makthe disk and force it into theopen end of mg Paper Bottles, of which the following is bottle lxrdy, a.third plunger which forces 60 1 1 a specification, reference being hadtherein 5 this top" downward in the body to its lower to theaccompanying drawing. end, and a pluiiger and die, which cut a Myinvention relates to automatic machines bottom from another stri'p, formor draw the for "forming and inserting tops and bottoms same and forceit also into the upper end of in boxes, cans, or bottles, and it isespecially the bottle, thus completing the structure, in 5 adaptedforuse in forming paper receptacles inverted position. The bottle bodiesare fed such as are used for contaming milk. The forward in series, stepby step, and located 5 bodies of such bottles are usually cylindricalprecisely in position, and the action of the paper tubes having papertops and bottoms plungers and dies is nearly simultafieous, which areboth adapted to fit closely within or, in other words, while a bottom isbeing the ends, respectively, of the tube. The botout and inserted inone body, a top is being tom is permanently fixed in the tube, but inpushed downward in another, atop is being 0 certain forms the top' isremovably placed out and inserted in a third, and a small disk inposition.

If, however, the flan econnected by a belt E the one on the left 45 extends downward, it hasnot-been a si'r'np e for cutting, forming. and in'sertin bottlematterto' form-and insert it' automatically;- tops in the upperfends ofthe butt es, and

This cutting,forming and inserting device has no novelty herein claimed, inconstruction or action. The plunger Ein rising-leaves the flanged diskin the upper part of the bottle body and by means of a crank plate i onthe crank shaft, a pitman G loose crank G", and common pawl and ratchetdevices G, the belt advanced one step, that step being an exact fractionof the distance between the axes of the two 'plungers' E, and is thusbrought to rest'in registry with a plunger H having a long hollow bodyprovided with a head H. to the upper side of which is hinged a plungerrod ll pivoted above to an arm H the opposite end of which is pivotallyattached to a portio rA of the frame. This arm is swung back and forthby means of a rod H", of adjustable lei'igth, pivot-ally coir ne'ctingitWvith a projection' II from the plunger rod of the plunger E. Theplunger H is closely'encircled by a loose sleeve H which itself slidesin a sleeve-like bearing H on the frame and is provided at its lower endwith an internally conical annular head H" to receive the upper end ofthe bottle body and hold the same in exact position.

The sleeve II frictionally engages the plnnger' and the friction isadjusted by means of a sleeve-encircling band H and a screw Il Thetension being properly adjusted the sleeve moves with the plunger solong no special resistance is offered, but the downward movement isarrested by the bottle itself,-after which the continued descent of theplunger forces the flanged top down fully to the lower end of the bottlebody :(see Fig. On the return of the plunger, the sleeve accompanies ituntil the head H meetsthe bearing If, after which the plunger continuesto ascend alone, 4 this being necessary, because otherwiscsome meansmust be employed to hold the plunger atr'est while other functions areperformed by other parts. If no means were provided to prevent, thesleeve would descend with the first downward movement of the plunger andwould reach its lowest point sooner than 4 is desirable. For this reasona spring I actuated. stop I is provided. This stop, moving in a way inthe sleeve bearing H passes ward until the incline lies in the wall ofthe sleeve, and as the 'latter is frictionally urged downward it in turnpresses upon the incline, forcing the stop farther outward out of thesleeves path, and descends with the further movement of the plungeruntil it meets the bottle body. \Vhen the plungers again rise, the isingstroke of the crank feeds the belt forward another step, and the entireoperation described is repeated.

After a certain number of steps in the ad- Vance of the belt, the firstbottle in the lower end of which a top was inserted comes to rest inexact registry with the second cut-ting die E and plunger E which act,precisely like the corresponding parts already described, cutting a diskfrom a second stock strip fed by rollers F as before, forming it,.

and inserting it as a flanged bottom in the upper end of the invertedbottle, after which the advance of the belt discharges the bottle readyfor parafiining. As shown, the upper fold of the belt is supported beloweach set of cutting and inserting devices by a removable block restingupon the bed of the frame and of a height equal to the interior heightof the bottle. In case, it be desired to produce bottles of doublecapacity, for example, to holda quart instead of a pint, these blocksare removed, allowing the belt to rest upon the bed, and the drivingwheel is turned backward, its pawl being lifted, to transfer the stockof the belt to the lower fold, and the upper end of the rod H is movednearer the pivot of the arm H so that the throw of the plunger H may becorrespondingly lengthened. In this case the bottle bodies fed by thebelt are of course correspondingly lengthened.

hat I claim is:

1. In a machine of the class described, the combination with means forfeeding bottle bodies to position, of means for insertin closures in theupper ends of said bodies, an automatic means for forcing the insertedclosures to the lower ends of the bodies, respectively.

2. The combination with means for advancing inverted bottle bodies stepby step,

closure in the body to the opposite end thereof, anda device carried'bythe plunger and s seaaeo adapted to hold the end of the bottle inaccurate adjustment while the plunger enters the same.

4. Tihe combination with means for supsition for engaging and adjustingthe end of the body prior to the entry of the plunger 7 therein.

5. The combination with means-for supporting a bottle body havingta toin its bot tom end, of a plunger arranged or pushing said top to theopposite end of the body, a sleeve lnolosing and frictionally engagingthe plunger and havin an end adapted for adjusting the bottle b0 y as itis frictionally advancing with the plunger, and means for arresting theretreating movement of the sleeve before the retreating movement of the.7 plunger is completed. I

6. The combination with an endless belt arran ed to advance a series ofinverted bot tie ies stepby step, of meansfor insert ing perf'oratedtops in the upper end of each i body during one of its periods of rest,means for pushing the inserted tops in suceession to the opposite endsof the body during subsequent periods of rest, and means for insertingbottoms in the bodies in succession during later periods of rest.

' 7. The combination'with an endless belt adapted to advance a series ofbottle bodies step by step, of means for supporting the upper fold ofthe belt at difierent heights according to the heights of bodies to beused, means for inserting bottle tops in said bodies in successionduring successive periods of rest, a plunger arranged to advance eachtop to thelopposite end of its body during a period of rest subsequentto its insertion, and. means for varyingthe throw of the plunger forbodies of different heights.

In testimony whereof I afiix my signature in presence 0 two Witnesses.
